  1. Anything with that may blades will always get some of the blades very dirty. paint it black. why did you go to a four blade prop?

    I did get the whole plane and the prop was convieniently attached to the rear.:D

    No ernest the 4 blade variable prop from MT gives a supersmooth ride, especially compared to the wood fixed pitch I had on my Long, talked with the builder of my Cosy and he wanted the 3 but got a good deal on the 4 blade.

     

    My Wife never liked the Long, not enough space, no view, felt seasick.

    The Cosy was the oposit, she loves it, and does not even get motion sickness, (If Mama is happy, is everybody hapy) YES YES YES..

  2. Very interesting to see that these carbon fiber cylinderhead covers have been produced.

     

    Most likely I will install a O 320 on the Long EZ. But even then I also wanna save every poung/kg I can to make it even better.

     

    Thanks for the link to the Italian company.

    :D :D :D :D

    Hi Ronny I work with them, and they shaved of nearly 10kg of teh standard O-320

  3. ronny don't worry an 800m strip is perfectly safe, especially since you are about seelevel and it does not get that hot in belgium. In Switzerland there are 5-6 varie/long ez operating out off birrfeld airport which is about 600m long. There is a guy in Italy flying a cozy out of a 800m strip. I personally consider 600m my limit to operate in safe conditions (of course maybe no overgross at 40C with strong X-wind) In my long I had an EFIS which gave me the takeoff distance (up to the 50ft obstacle) and best was 250m (alone, wintertime, seelevel, 2h fuel, no wind) worst 550m (2 full fuel, slightly overgross 40C) wolf.

  4. General build question, I have a half build Varieeze project, wings, canard are done, the fuselage is still missing the bottom and the outside glass. The Pu foam is sundamamged and I will substitute it. Now my question PU and PVC foam is cumbersome to get here in Italy, what speaks (apart from a possible fuell leak) against using Polystyrenfoam (the same density) for the fuselage bottom, sides, nose and canopyframe??:D I guess the PU has been selected by Burt because of it's insolubility in Gasoline?

  5. Hi there, the family has grown and I need more than 2 seats, therefore I like (don't realy like to) to sell my Long Ez, German Experimental located in Italy, 380h since new 1993. O-290 D2 430h TTSN and 70h STOH, Panel new with EFIS, radio, transponder, ELT.Cockpit painted, new tires, prop... A blast to fly (honest 140Kts cruise at 24L/h) and can only be substituted by another canard (need the funds to buy a COZY or COSY)

     

    If Interested PM me

  6. there is a 3300 jabiru on sale on the avaizione leggera site for 13k€ (there is a guy at ancona installing the 3300 in a varieze. Or look for a rotax 912 or a Sauer 2100 turbo.

    By the way I am in Pescara, fly a Long and restore a Varie

  7. Hi guys I resolved my speed brake trouble, it was the pilot I had 3 times surgery to get rid of a gut cancer and was just to weak for my speed brake, now after some time I regained my strenght and the speed brake can be deployed without much trouble:cool2:

  8. I knew that the first Varies sideslipped could under some conditions depart from controlled flight and I read that Burt limited the rudder travel to prevent that. The Varie I flew is from 83 and so far in testing I have slipped it quiet agressively and did not loose it (the carft has 400h, but after restructuring I test flew it again, so lots of altitude and a chute) The craft is heavy, 780lbs so anyway I aproach fast and that day because of the gusts I was at about 100KIAS (no speedbreak)

    To cut ist short this Varie seems to not depart

  9. This does not happen to me!

    There I was today test flying the restored varieze of a friend (the EFIS did reboot often and we harrowed down on the problem) nice weather CAVOK a little bit windy 18kts 28gust but 230degree wind and a 22 runway. Just hoped around the pattern quite turbulent, decided to go back got a direct base (you see it coming) decided to leave the speed brake in due to the wind (on final we had 50kts ground and 88KIAS, perfect short final slightly slipped into the wind, perfect touchdown no drift at all (I felt pride swelling up) until it made bonk and we landed on the nose!!!!!!!!!! stoped told the tower that we "tested something" put down the electric gear and taxied back. The Damage was slight (apart from my pride), my friend had installed a steel mount with a Polypropylene wheel. We ground the wheel off and part of the mount (and 5mm of the transponder antenna). I will post a picture of the installation. no heat damage to the rest of the structure and we landed fairly fast (the varie weighs 780lbs) so 80KIAS whatever that was in groundspeed with that wind.

     

    learnings:

     

    Install a gear warning

    follow the checklist

     

    I keept the ground of steel mount as my clubsign (gaerupers)

  10. Confused??? Isn't that most of the time when flying???:rolleyes:

    yep but but pushing it around the compas rose on the ground (gear down) to compare the real headings with your compass and then fly with the gear up and some steel closer to the magnetic sensor will get you different readings, still confused?

  11. I have an EFIS from MGL and put the magnetometer in the spare, did not work, the engine is to close, I ended up installing it under the frontseat, works good, you only have to compensate with the gear up.

  12. Thats a good point I will check if something is caught in the mechanism.

    Sounds pretty weird. Are you sure that your airspeed indicator is correct? Check to see what speed the board auto retracts---needs to close at 95 kts.

     

    Landing brake springs need to be adjusted so that you have a 40lb pull on the trailing edge of the brake to close it. If it pulls closed with less than 40 lbs, you need to tighten in up. If more than 40 lbs, you need to loosen it.

     

    Seems strange that it is easy to operate on the ground---sort of eliminates any binding problems---unless you have stuff that can shift in there while airborne (is the opening in the side of your armrest such to get your coat or seat cusion caught in the device?

  13. Dear Sirs, lately I am having more and more difficulties extending my speed brake (a plain vanilla O-290 Long Ez, which I did not build) even at 60-70kts I need both hands where before at 90 one hand was enough, on the ground it feels light. Am I just getting week or did something shift in the mechanic which I am to blind to see??

    Any advice wellcome

  14. gentlemen, I aquired a turbmeca pallas jet engine (70kg engine weight and 160kg trust) which I plan to install in my Varieze. :DThe motor fits then engine compartment quite nicely, has enough trust, is a real aircraft engine (no modified apu or targetdrone engines), is actually lighter than a O-200, the only drawback is its substancial thirst (120L/h at cruise)

    No to my questions,

    how can I modify the varie to allow for higher speeds safely?

    I need extra fuel tanks, what's better 1 tank under the fuselage or 2 smaller ones underneath the starkes?

  15. Guys I need the prop size which the VE airframe geometry would allow if I would retract the prop station by 8" (Don't want to take the VE of my friend and and tilt and measure (rather cumbersome) once I know the max I will talk with the engine designer (since I am opting for a light geared engine I will install one of the new light CS props anyway)

     

    wolf.

  16. What would you gain by a longer prop? the prop still has to drive the same aircraft at the same speed with the same HP. if the prop is longer then it may need to be thinner or different blade shape. what does being geared have to do with it. the faster vari ezes are running 3000 + RPM and they use shorter props

    the faster VE are using direct drive engines and you have to run them high for max power, 3000+ needs a short prop to remain efficient. (Actually I was still not able to find out if the short prop recomanded by Burt is due to the high engine RPM of the O-200 or the chance of Propstrike)

     

    But a geared engine can turn the prop slower and a bigger prop with higher torque is more efficient (especially if it is a CS) (propulsion is impulse (v x m) so more air at lower speed is more impuls, that's why jet engines are inefficient at lower airspeeds)

     

    SInce the VE suffers from high weight and back CG any engine which is lighter and shorter will be of benefit, my question remains -8 inch in prop station how much bigger can the prop be???

     

    wolf.

  17. In restoring my VE I will install a BMW Motorcycle 2 cylinder engine (which is being sucessfully used since 20 years, up to 125hp out of 178lbs installed). The engine is about 8 inches shorter than a O-200. If I have my prop station 8 inch advanced I can install a longer prop (the engine being geared a longer prop would make sense)

    Now my question, does a longer prop make sense on the VE, if yes how much longer can it be??
